This work is devoted to the study of tribological characteristics of polymer materials in a friction pair with steel. Tasks that were solved during the study: 1. Choose materials for research; 2. Conduct a preliminary assessment of samples; 3. To test samples on a PBD-40 type friction machine; 4. To test samples on a friction machine of the MTVP type; 5. To evaluate the results of tests on friction machines using microscopic examination; 6. Test samples on a stretching machine and determine the Youngs and Poissons ratio of materials; 7. Create a mathematical model of material testing on a PBD-40 type friction machine. Comparative tests were carried out on friction machines according to the schemes of spinning friction and sliding friction, as well as stretching of samples from ABS, PLA, PLA+, PET-G and digital modeling of the test results according to the scheme of spinning friction. As a result, the data obtained for all the studied samples were analyzed, graphs of the dependencies of the moment and friction force on time, stretching diagrams, as well as stress and displacement distribution plots were obtained. Based on the conducted research, it was decided to reject PLA and ABS among the studied materials. PET-G and PLA+ have the best characteristics in a friction pair with steel.
